HOT-WATER RADIATOR.

Specification of Letters Patent.

ented- M r 1e1 Application filed April 3, 1913. Serial Np.;758 ,678.

To all whomit Hwy concern Be it known that-I, SrUARr ELLIS, a Cltl- Zen of the United States, residingwat ash:

ington, in the District ofColumbi-a, have invented new and usefulimprovements in Hotater Radiators, of which the follow ing is a specification. e general ob ect of this invention is to,

improve upon the hot-water heater shown in the patent to C. M. Nheelock, #882,436, dated March 17 1908, for an improvement in hot water heaters.

Specifically, the object is to provide a structure wherein the burner may beheld in spaced position withrelation to (that is,

out of contact with) two of the radiatorsections. between which it is placed, so that the air to support combustion, admitted at a point below said-burner, may have free access to said burner and pass thereby, on each side thereof.

Objects of improvements, not specifically mentioned, going to make up the ultimate perfection of the device as an entirety, will appear as the specification proceeds, and the nature of the invention morefully appears.

In the accompanying drawings, forming part of my specification,- I have illustrated a form of embodiment of my invention capable of carrying out the underlying principles thereof, and in these drawings, in which like reference-characters denote corresponding parts throughout the several views: Figure I is a side elevation of a radiator embodying my improvements; Fig. II is a transverse section on the line 22, Fig. I; Fig. III is a horizontal sectional view on the line 33, Fig. II, looking in the direction of the arrow thereon; Fig. IV is a fragmentary sectional view of the burner and the two adjacent radiator-sections between which it is disposed, showing the spaced relation of said burner to said radia- 1 accidental downward movement.

upper ends 6, 6 of theshield are bent inward and. toward each other, so as-to engageandbear upon the top of the radiatorsections 21and 3. The radiator is provided, also, with a gas-igniting aperture 7, normally covered or closed by a sliding door 8, wh ch pro ects, at its sides,under guiding- .strips. or tracks 9, 9, carried by the shield 4;

and bent. inward at their upper ends, as

there; will be sufficient degree offrictional engagement between said door and said track-ends 10, 10 to hold the former against 'l heshield 4 is also provided, at a suitable point he neath said aperture 7, with air-inlet holes 11, and, between said holes 11 and said aperture 7 ,1 with oppositely disposed openings 12, 12, through'which projects aburner 13.

Said burner 13 isprovided, in its top, with a longitudinally-disposedseries of transverse-ly-extending slits 14. .T he burner preferably carries, at one end thereof, a flange 15, in this instance integral therewith,

:and bearing exterior-1y against the shield 4.

The burner terminates, at its other end, in a screw 16,,projecting through a clampingplate 17 bearing exteriorly against the shield 4;. The plate 17 and flange 15 are held tightly against the shield 4 by an adjustingnut 18 threaded on the screw 16. It will be seen, also, that, since the flange l5 and the plate 17 bind tightly against the shield -1 when the nut 18 is tightened up, the shield is in turn, caused to bind tightly against and thus be clamped to the radiator-sections 2 and 3. The flange 15, the plate 17, the screw 16, and the nut 18 thus subserve the dual function of holding the burner 13 in position, and, also, of holding the shield 4 in position.

It will be noted that, by the burner-clamping and supporting-means, just described, the burner may be held out of contact with the radiator-sections 2 and 3, so that air from the air-inlet openings 11 may pass freely upward between the sides of said burner 13 and the inner sides of the radiator-sections 2 and 3.

19 is an air-mixer, of any suitable construction, carried by a tube-section 20 carried, in any suitable manner, by the burner 13. The tube-section 20 is preferably curved, as shown, so that the longitudinal axis of the air-mixer 19 lies in a plane parallel with I shown at 10, 10, so that, when the door is raised to the limit of its upward movement,

the shield l, instead of at right-angles thereto. K have found, in practice, that the elhow of the curved tube-section 20 tends to prevent flare-backs of the gas, when lighted initially through the opening 7, as said elbow presents a certain amount of obstruction to the gas.

The radiator 1 is provided with the customary upper and lower horizontal connections 21, respectively, establishing communication between the upright sections 23 of the radiator, as usual. In addition, the radiator is provided, toward the lower end thereof, above the lower series of connections preferably at a height of one-third the distance from the bottom of the radiator, with a third series of horizontal connections 24, each of which connects and thus establishes communication with two adjacent vertical radiator-sections, there being no connection 24 bet-ween the vertical radiator-sections 2 and 3. The object of this third series of connections 2% is to provide for circulation when the level of the water is below the upper series of connections 21. The radiator l is provided, at its upper end, with an exit-tube 25, internally threaded at its outer end. In said threaded end of the tube 25 is disposed at valve-casing 26, carrying a check-valve '28, serving the function of a safety valve.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is:

1. The combination with a hot-water radiator or heater, formed of a plurality of parallel, upright sections, of a heat-confining shield disposed between two of said sections, and means for holding said shield in position on the radiator, including: a burner extending between said two sections and having means at one end engaging said shield and a screw-threaded opposite end,a clamping-plate engaging said shield and through which said screw-threaded end projects, and an adjusting-nut carried by said screwthrcaded end and engageable with said clamping-plate.

'2. The combination with a hot-water radiator or heater, formed 01" a plurality of parallel, upright sections, of a heat-confining shield disposed between two of said sections, and means for holding said shield in position on the radiator, including: a burner extending between said two sections and spaced therefrom and having means at one end engaging said shield and a screw-threaded opposite end, a clamping-plate engaging said shield and through which said screwthreaded end projects, and an adjusting-nut carried by said screw-threaded end and engageable with said clamping-plate.

in testimony whereof, I have hereunto set.

my hand in presence of two subscribing witnesses.
